I am installing a new ES120 plotter, with
radar and a new evo 400 pilot with an octopus hydraulic ram. I will also be installing about 1000w of
solar through an
MPPT and possibly a
wind generator. All of these things are at the back of the
boat and the
batteries are 30 ft forward.
If I run the plotter,
radar and pilot straight from the 12 volt distribution panel than I will need to run about 25 ft of wire each way for each system. I will also need to run
power wires for the
solar panels back about 30 feet back to the
battery box. Thats a lot of wires and it is not so much the cost of the wires as the space they need. I am running out of space. Who would have though you run out of space on a fairly large 50 foot
boat.
What I am considering doing, is running a positive and negative 4/0 through the boat to act as a
power bus. I would then take power off of this using relays to switch the chart plotter , radar and auto pilots from the main distribution panel. So control would be in the same place but actual power would come from the bus with lots of power available through the bus. I would keep extra relays on board in case they failed. Individual components would be fused as appropriate and I would put a 500 amp fuse on this 4/0 bus
I would then also hook up the output from the
MPPT controllers to the 4/0 bus to send power back to the
batteries from
solar and possibly
wind.
I am not an electrician or an
electronics guru so I am here to ask some questions.
1) Is this set up safe?
2) Is this set up practical?
